Olham? Can this be the same 'Olham' who has been telling us what an ugly aiplane the D.VII is? A 'railroad box-car' of a plane? A 'soap-box racer' of an airplane? [i'm quoting from memory here.] Can it be?
Don't let GMAX scare you off. If you can turn the computer on, you can handle 3D applicatrions. The first is the worst. [After the first one, they all work in similar ways.] Download the article above that StumpJumper posted. Lots of good stuff in it. The tutorial I'm using you can find at www.simviation.com/gryphon/tutorials/gMax_02.htm He starts you off building a WWII German jet [Me-334] Not exactly our cup of tea, but, just this once, I'm going to follow the tutorial and NOT jump into my pet project at once and try to adapt the tutorial to it. One good piece of advice, [i believe it was in Stump's posting], the author says 'For your first plane, build something very basic, even rudimentary. Same with the second'. Don't try to make some that looks really hot. Get the basics under your belt...then go for 'pretty'.
Also, I found 'The G-Max Bible' on amazon.com [i always buy Used copies.] There are other sources. I've got a bunch in my Favorites file. I'll dig them out later and post them. Among them: a G-Max Forum where you can question experienced people. And then, there's us. I'm sure the three of us can get one airplane off the ground.
EDIT: 'Checked the Favorites file. The best entries are the ones I've already posted here.
